# Given a `date` string in the form `Day Month Year`, where:
# 
#   * `Day` is in the set `{"1st", "2nd", "3rd", "4th", ..., "30th", "31st"}`.
#   * `Month` is in the set `{"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"}`.
#   * `Year` is in the range `[1900, 2100]`.
# 
# Convert the date string to the format `YYYY-MM-DD`, where:
# 
#   * `YYYY` denotes the 4 digit year.
#   * `MM` denotes the 2 digit month.
#   * `DD` denotes the 2 digit day.

#     Input: date = "26th May 1960"
#     Output: "1960-05-26"
#     
#
